如何绑定到C# wpf数据网格视图单元格的背景？

<DataGrid ItemsSource="{Binding YourDataCollection}">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Binding="{Binding Name}">
            <DataGridTextColumn.CellStyle>
                <Style TargetType="DataGridCell">
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding Name}" Value="John">
                            <Setter Property="Background" Value="Green"/>
                        </DataTrigger>
                        <DataTrigger Binding="{Binding Name}" Value="Alice">
                            <Setter Property="Background" Value="Yellow"/>
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </DataGridTextColumn.CellStyle>
        </DataGridTextColumn>
    </DataGrid.Columns>
</DataGrid>
